This package is from the 5.6 LTS branch, which continues to have support
for the Broadcom-based first generation of 802.11ac access points (UAP-AC,
UAP-ACv2, UAP-AC-Outdoor) and the Atheros-based but limited-memory
Picostation M2.

For other devices (including the older Atheros-based 802.11n access points)
the stable branch is recommended instead.
